Blue one should be a triangle (only 3 vertices) others are ok with 4 vertices.

We are picking the 4th vertice as not missing

import numpy
import vcs

x=vcs.init()

data_values = [ 25, 45, 55.]

data_lon = [ 5., 10., 15.]
data_lat = [ 5., 10., 15.]

data_lon_vert = [ 
        # Triangle (last one missing because traingle has only 3 vertices
        [2.5,7.5,5.,1.e20],
        # Square
        [7.5,12.5,12.5,7.5],
        # Diamond
        [15.,17.5,15,12.5],
        ]

data_lat_vert = [
        # triangle
        [2.5,2.5,7.5,1.e20],
        # square
        [7.5,7.5,12.5,12.5],
        # diamond
        [12.5,15,17.5,15],
        ]

mesh = numpy.array([data_lat_vert,data_lon_vert])
print "MESH SHAPE:",mesh.shape,mesh.dtype
mesh = numpy.transpose(mesh,(1,0,2))
print "MESH SHAPE:",mesh.shape
mesh = numpy.ma.masked_greater(mesh,1.e19)

print "Triangle lats:"
print mesh[0][0]
print "Triangle lons:"
print mesh[0][1]
m = x.createmeshfill()
m.mesh = True

x.plot(numpy.array(data_values,),mesh,m)
raw_input("press enter")
